Insulation Company in Highland, CA
Woolsey Attic Insulation is the attic and spray foam insulation company built for Highland’s specific conditions: scorching summer afternoons that turn attics into 150°F ovens, then cold mountain air that rolls down from the San Bernardino foothills after dark. Most Highland homes date to the 1965 – 1995 building boom, which means code-minimum fiberglass batts and energy bills that punish homeowners all year, not just in August. We give every Highland homeowner a written price before work starts, show up in the promised window, and stand behind the job in writing for 365 days. Call (325) 240-5411 for a free estimate.
Why Highland Homes Are Different
Highland sits at the base of the San Bernardino Mountains, and that geography creates a thermal double-bind most of the Inland Empire doesn’t feel as sharply. Summer days routinely exceed 105°F and push attic temperatures past 150°F. Then clear nights send cold katabatic air draining down the foothills, and interior temperatures drop fast. That daily swing means insulation has to do two jobs at once: block daytime heat from baking the living space, and hold warmth in after the mountain air arrives. Most of the homes we walk into were built between 1965 and 1995 with R-11 to R-13 fiberglass batts in the walls and thin attic layers that met old code but leave modern energy costs nowhere to hide. It’s a different workload than the flat-valley cities. And because many of these tract homes sit on slab-on-grade foundations, the attic and garage ceiling are often the only accessible insulation layers, so getting them right matters even more. With cold mountain nights in the foothill-adjacent streets like East Highlands and the neighborhoods near Greenspot Road, we’re correcting insulation that was undersized when it was installed and has only lost performance since.
Our Main Highland Services
Homeowners in Highland call Woolsey for two things most often: attic insulation upgrades and spray foam air sealing. Each one gets its own detailed page below.
Attic Insulation in Highland
The most common job in Highland is bringing attic insulation up to modern R-value. Older tract homes here top out around R-11 to R-19 in the attic, and a 150°F attic over a slab-on-grade home means the heat pushes straight down into the living space all afternoon. We remove the old compressed batts, air-seal the penetrations, and blow in fresh insulation to current code levels. Because Highland’s nightly temperature swings cycle moisture through poorly ventilated attics, we also check for compressed or moisture-damaged insulation before installing anything new. Get the full breakdown on our Attic Insulation in Highland page.

Spray Foam Insulation in Highland
Spray foam, a two-part liquid that expands on contact and seals gaps airtight, answers a specific Highland problem: the cold air that drains down from the San Bernardino Mountains on winter nights. In homes with uninsulated garage ceilings that border living space, or walls too thin to hold back the temperature swing, spray foam creates a continuous thermal barrier that fiberglass batts can’t match. It also locks out the dust and pollen that blow through Highland’s valley air. Learn what’s involved on our Spray Foam Insulation in Highland page.

What pushes a Highland job toward the top of those ranges is usually the home’s construction: 1970s and 1980s tract homes often have awkward attic access, old wiring running through the blow area, and compressed or moisture-damaged material that has to be removed first. Whatever the number is, you’ll have it in writing from Woolsey before any work begins. That’s how every job runs, no exceptions.
